The critical speed of ball mill is given by, where R radius of ball mill r radius of ball. For R 1000 mm and r 50 mm, n c 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 1530.7 48.86 of critical speed.
Free quoteThe speed of rotation of the mill determines three basic types of operation modes slow rotation cascading, fast rotation cataracting and very fast rotation centrifugation. Each type is characterized by a specific trajectory of motion of the charge in the mill and a different impact of the milling bodies on the ground material.
